Out of curiosity I tried to do some looking around on them. Most of it was just PR news related and proxy stuff. The MLM "watchdog" sites where they were even mentioned just had contact info.
My impression, since I'm posting anyways, is that they appear to be credible but are a MLM program. If you're cool with MLM then maybe you'd be cool with these guys.
Personally I don't like MLM; too much like church politics if you ask me.
